According to the data-signal that provides from switching transistor ST, driving transistors DT conducting and control flow to the electric current of organic illuminating element OLED from driving power supply line VDDL.
Capacitor C is connected between the grid and fundamental power supply line VSSL of driving transistors DT, and stores and be supplied to the corresponding voltage of data-signal of the grid of driving transistors DT.Capacitor C remains on normally on low-voltage with driving transistors DT in an image duration.
Pixel-driving circuit can also comprise at least one compensation transistor and compensation condenser (not shown), the threshold voltage of its compensation for drive transistor DT.And pixel-driving circuit can also comprise the ballistic transistor (not shown), is used for optionally will being fed to organic illuminating element OLED from the electric current that driving transistors ST provides.
Organic illuminating element OLED is connected electrically between the source electrode and fundamental power supply line VSSL of driving transistors DT, and according to the corresponding galvanoluminescence of the data-signal that provides from driving transistors DT.For this reason, organic illuminating element OLED comprises anode (perhaps pixel electrode), and it is connected to the source electrode of driving transistors DT; The organic layer (not shown), it is formed on the pixel electrode; And negative electrode (perhaps reflecting electrode), it is formed on the organic layer.Here, organic layer can comprise hole injection layer (HIL), hole transmission layer (HTL), emission layer (EML), electron transfer layer (ETL) and electron injecting layer (EIL).
Among sub-pixel R, G, B and the B2 each is according to depending on that the conducting of the driving transistors DT of data-signal controls the level that flows to the electric current of organic illuminating element OLED from driving power supply line VDDL; And therefore luminous, thereby show particular color from the emission layer of organic illuminating element OLED.
Based on the luminous organic material of the emission layer that is formed for realizing particular color, sub-pixel is divided into the red sub-pixel R, the green sub-pixels G that comprises green luminous organic material that comprise red luminous organic material, comprises first blue subpixels B1 of sky blue luminous organic material and the second blue subpixels B2 that comprises the mazarine luminous organic material.
As shown in the luminance graph of Fig. 2, according to the voltage " Voled " of sky blue and mazarine organic illuminating element OLED, the first blue subpixels B1 and the second blue subpixels B2 have the different brightness characteristic.Promptly; When same voltage " Voled " was applied to the first blue subpixels B1 and the second blue subpixels B2, the brightness of the first blue subpixels B1 that comprises sky blue luminous organic material was usually above the brightness of the second blue subpixels B2 that comprises the mazarine luminous organic material.
